SPECIFICATION forming part of Letters Patent No. 483,147, dated September 2'7, 1892.

Application filed July 25, 1891. Serial No. 400,728- (No model.)

To all whom it may concern.-

Be it known that I, BENJAMIN GOLDENBERG, a citizen of the United States, residing in the city of New York, county of New York, and

a State of New York, have made new and useful Improvements in Locks, of which the following is a specification.

My invention has for its object to direct the performance of an act through the performance of another, and the specific class of devices used in the accomplishment of this is found in the class of key-traps, and, among others, the specific act which I shall describe herein as illustrating the method of using my invention is the closing or shutting off of the water in a main by means of a valve located in a house in order to permit the locking of the house-door, these two elements being preferably in the same house, although not of necessity so.

It will be apparent that my invention can be applied to the performance of acts not specifically noted herein, such as the switching off of an electric current prior to and permitting the sealing of an opening closed by a window, door, &c. It must be apparent that the combinations and kinds of acts that may be made mutually depending upon one another are quite extensive.

My invention further consists in the details of structure and combination of parts herein, among the many features of which is a device for rendering the movable parts of the look more inaccessible than usual, so as to prevent, or at least render less possible, the picking of the look, all of which will be hereinafter set forth.

In the drawings, Figure 1 is a side elevation of the lock, the key in the lock, the cover of the lock being removed, disclosing its interior, a service-pipe and cock, and a bracket and bed, illustrative of the position of the parts during the operation of approaching the lock to the cock to release the key; Fig. 2, a side elevation of the lock with the cover removed to illustrate the mechanical union of the valve-stem and position the movable parts occupy with relation to each other during the act of removing the key from the lock to permit its use in the unsealing of some other aperture or the performance of some other act; Fig. 3, an end elevation of the right-hand end of the lock, a portion of it being broken away to disclose its interior, a key inserted and detained therein and cut in two on the line a: an, Fig. 1, for the purpose of preventing confusion of parts; Fig. 4, a left-hand end elevation of the lock and bracket, the bracket being in section, taken on the line y y, Fig,

1; Fig. 5, a perspective view of a detail of the lock mechanism which prevents the automatic union of the lock and cook, except when the same are properly united; Fig. 6, a detail of the lock mechanism for operating the element shown in Fig. 5; Fig. 7, a detail of the lock mechanism.

, Same figures of reference indicate like parts throughout the several views.

In the drawings, 1 is a cock, valve, or switch controlling a supply of water, gas, electricity, or any other material for the consumption in a building, and 2 a main or supply pipe leading to the valve.

3 is the valve-stem.

The cock can be supported in any desirable manner-as, for instance, to a wall, as at 4. The valve-stem 3 is provided with an out Wardly-extending finger 5, shouldered at 6, which can either move right or left, for the purpose herein set forth. A bracket 7, provided with an outwardly-extending bed 8, is secured to the wall 4 under the valve 1 in such a way that the bed 8 will be located directly under the valve-stem 3 when it is turned to shut off the gas, water, (he. Secured to the bed 8 is a plate 9, having lapped side 10, which is adapted to engage with projections 11, formed on the lock. The plate 9 I shall call the guide-plate, and its function is to guide the lock up to the valve-stem when the conjoint act of shutting oif the water and releasing the key is being performed.

The left-hand end 12 (in the drawings) of the casing of the lock is provided with an upwardly-extending slot 13, and the bottom wall 14 of the lock-casing is also slotted, as at 15. At a place on the guide-plate 9 aligning with the slots 13 and 15 is located a thin metallic strip 16, which when the lock is moved toward the cock will enter the slots and operate in the manner hereinafter described. The strip 16 is rounded at one end, as at 17, to enable it to better engage the mechanism of the lock.

The lock-casing comprises the walls 12 14;

ICO

' 18 19 and side plates 20 21, the plate 21 being adapted to be removed from the casing and secured thereto by the projections 2223', which pass through holes in the plate 21. The casing can be constructed in' any desirable man- 1161'.

At the right-end portion of the lock-casing is formed a chamber 24, divided off from the main portion of the casing by the septum .25. The key-spindle 26 is secured to the septum and projects toward the end plate 19 of the casing, said plate being apertured, as at 27, Fig. 3, to conform to the shape of the heel 28 and toe 29 of the key 30; The end plate 19 may be made so as to be readily removable to enable various conformations of key and accompanying devices to be attached to various locks, which will permit the use of variouslyconformed keys with the same look, thereby obviating the necessity of making a new look for every differently-shaped key-that is to say, bythis a differently shaped or conformed key can be used with the same locking mechanism without changin gany other part of the particular lock than the removal of the keyway. Both the septum 25 and end plate 19 can be united into one elementfor the same purpose, and either the end plate 19 alone or that and the septum 25 will be termed the keyway in the claims, unless otherwise designated. These keyways can be made to conform to the standard styles of keys and locks and can be interchangeable with my lock whenever it is so desired.

I Secured in the sides 20 21 of the lock-casing and extending across the interior there of is a spindle 31. Upon this spindle is r0- 7 tatively supported what I term the boltplate 32, which has extending therefrom the segmental bolt 33, the function of which is to enter between the shoulders 6 of the finger 5 of the valve-stem when said finger is moved into the lock, and by means of which the lock and valve are mechanically united.

The main body of the bolt-plate, or that portion which surrounds the spindle 31, is preferably made concentric with the said spindle. Opposite the bolt 33 is formed a segmental rack 34, the teeth 35 of which extend through a slot 36 cut in the septum 25.

squared sections in their turn abut against the wall 21 of the lock-casing, thereby limiting the oscillation of the rack 40 when moved in either direction. The toe 29 of the key 30 A shoulder 37, formed on the bolt-plate, engages enters one of the teeth of the rack40, which teeth may be spaced. To permit this, a portion of the rack cut away will be found most convenient. It must now be plain that if the keybe turned to the left (considering Fig. 3) the bolt-plate must be vibrated and the finger-bolt 33 moved up and past an opening 43 cut in the plate 12 of the lock-casing, so that when the finger 5 is inserted in this opening, as in Fig. 2, the bolt 33 will pass between the shoulders 6 and secure the valve-stem within the look. It is not intended, however, that a movement of the key to the right (considering Fig. 3) shall throw the bolt, as this is the function of the spring 38, for should the bolt 33 be capable of movement up and down by means of the key 30 it would not be necessary to mechanically unite the valve-stem and lock together in order that a removal of the key may be obtained. It is only intended that a movement of the key to the left to free the bolt from the valve-stem should be had, the squared section 42 of the segment 40 limiting the throw in this direction. The movement of the key to the right is prevented by the dog 44 engaging with the detent 45, formed in the boltplate. \Vhen in this position, the toe 29 of the key 30 is held out of alignment with the opening 27in the plate 19, so that the removal of the key from the lock is prevented until the dog 44 is thrown out of contact with the detent 45.

The dog44 when released from the detent 45 by the insertion of the valve-stem into the lock permits the spring 38 to throw the bolt 33 into the position assumed in Fig. 2, the detent then pressing against the under surface of the bolt-plate 32. The dog 44 is carried by or formed upon the rocker-arm 46, rotatively supported upon the short spindle 47. The opposite end of the rocker-arm 46 is provided with a striker-plate 48, against which the finger 5 strikes when it is moved into the look. A spring 49, secured upon the spindle 47, engages at one end with the striker-plate 48 and ICC at the other end with the spindle 31, sothat I when the parts are moved to bring the detent 45 in alignment with the dog 44 the spring will operate to throw the dog back into the detent.

The mechanism before described, when properly constructed and operated, will suffice to secure the performance of the acts herein spoken ofthat is, it will render necessary the mechanical union of the lock and valve (thereby shutting off the water) to permit the key to be withdrawn from the lock to enable the house-door to be again sealed with the same key.

Should the bolt 33, by reason of the breaking or disengagment of the spring 38 from the shoulder 37 of the bolt-plate, have a tendency to drop down so far that the teeth 41 on the rack 40 should be thrown past the opening 27 in the plate'19, so as to prevent the key being inserted in the rack 40 to release the valve and lock, the squared section 41 will be brought up against the wall 21 of the valvecasing, and thereby prevent such abnormal which finger will strike the striker-plate 48, release the dog 44 from the detent 45, permitting the spring 38 to throw thebolt 33 between the shoulders 6, at the same time turning the rack 40 so as to bring the toe 29 of the key 30 into alignment with the opening 27 in the plate 19, thus permitting the removal of the key. However, in order to make the removal of the key from the look without the mechanical union of the valve and look more difficult I use thefollowing mechanism, to the specific detail of construction of which, however, I do not limit myself: A plate 50, Fig. 5, having a slot 51 and pins 52, is movably supported against the wall 20 of the lock-casing. A guide 53, Fig. 7, is formed thereon and works within the slot 51 andpermitsits upward and downward movement. Anotherguide 54, working in a slot 54, provided for it in the plate 50, may be used toassist in preserving the plate in a perpendicular position; but this I do not consider essential. An arm 55 is formed on the plate and is adapted to open and close the aperture 43 in the lock-casing, so as to prevent the strikenplate 48 being surreptitiously operated to free the dog 44, it being necessary in order to remove the arm from in front of the aperture 43 to place the look upon the bed 8 of the bracket 7. A bell-crank lever 56, Fig. 6, is pivotally supported upon the spindle 47, the lower end 57 of which has an outwardly-extending arm 58. The upper end of the lever 56 enters between and engages with the pins 52 on the plate 50. A projection is formed on the guide 53 (see Fig. 7) to limit the upward movement of the arm 59 of the lever 56, the lower end of the spring 38 engaging with the arm 58 and tending to keep the arm 55 constantly before the aperture 43, except when the same is moved downward by the arm 58 coming in contact with the metallic strip 16, as shown in Fig. 2. When this happens by reason of the lock being guided to the valve-stem to unite them and free the key, the arm 59 of the lever 56 is vibrated downwardly, moving with it by reason of its engagement with the pins 52 the plate 50 and with it the arm 55. The contact of the metallic strip 16 and the arm 58 is preferablyso timed that the upper portion of the slot will be past the aperture the moment the finger 5 on the valve-stem enters it.

Many changes and modifications may be made in my device without departing from the spirit of my invention.
